Why is your 1993 Altima Nissan making a clicking noise but does not start?
start by checking a/c compressor.
if its a low knocking noise it is normal on the 3.1 engine!! if it is loud check to make sure the valves are getting oil!! I have a 2000 Malibu v6 and it is the same way.
if you turn the key and nothing is making noise check the battery if you are trying to start it and it is making noise press the gas a little bit so that the car can pump gas into the engine
There could be numerous reasons why a Suburban is making engine noise at start up. It could be anything from a blown gasket to a spark plug. A mechanic will be able to find out the cause of the noise.
== == I do believe if you hear a knocking noise that your crank shaft could be failing. Which means you will need a new engine. Have it checked out. Replace the harmonic balancer they will make a bad knocking noise. When you start it and the oil light goes out and it knocks, this is what is wrong with it.
It could be the supercharger snout itselft. I just replaced mine because it was making a sort of knocking noise. I started out just hearing it at start up and turning it off. Mine runs like a champ now along with a smaller pulley and an exhaust job.
Fuel pump
One way you can tell is if there is a knocking noise or rattling noise when you start the car. Also, the belt may keep making the noise until you accelerate over about 2500 rpm...depending on the vehicle. Check to make sure the belts arent too tight or too lose. If all else fails the best thing to do is let a shop look at it.
fan motor might be bad.
because it gets old dummy
the battery is flat
